DESCRIPTION
The Battery Guard BG40/60/100/200 (hereafter BG) is an intelligent, fully waterproof,
battery guard with expansion capabilities for an on/off switch, alarm buzzer or relay
and our Battery Watch (not supplied). To ensure low losses, the BG is provided with
two screw terminals, one Input+ and one Output+. The rest, like the minus and the
accessories are connected via four 6.3 mm faston connectors. The LED indicates the
output status (on/off) of the BG and in the programming mode the LED indicates the
program position. The BG is provided with an ‘Automatic board system detection’
with which the BG automatically detects what the battery voltage (12V or 24V) of the
system is, so that it does not need to be set manually. Both under and reset voltage
thresholds can be easily programmed.
INSTALLATION
Mount the BG on a cooling (metal) surface so that it can release the developed heat.
Connect the BG as close as possible to the battery (maximum distance: 50cm).
Only in this way can the voltage be monitored exactly. Any programming of the
BG must take place before the equipment (users) can be connected. For the minus
connection use a cable of 1.5 mm2 which goes directly from the battery to the BG
and do not use this connection for anything else.
Warnings:
• The product should only be connected by skilled fitters / mechanics, who are
aware of the regulations for working with high battery voltages.
• Live parts must not come into contact with the housing of the BG.
• Use of bad material and / or too thin wires can damage the BG.
• A short circuit between the positive and negative terminals of the battery may
cause severe damage to your system.
• Always use fuses (of the correct value).
OPERATION
In the standard programming (position 11 in the “Configuration Table”) a buzzer
may be connected to the alarm output. This will sound an alarm after 15 seconds
when there is undervoltage. If the situation does not change, the BG will turn off
attached devices after 75 seconds and the alarm will be switched off. Since with
overvoltage there is a risk of damage to the connected equipment this will be
switched off immediately when there is overvoltage (16/32V) and the alarm output
will pulsate. This is done to distinguish between an undervoltage alarm and an
UK

3
overvoltage alarm. A second application is to connect a relay to the alarm output.
The BG must then be programmed in position 12 (see “Programming”). The relay will
switch on during an alarm and only switch off when reaching the reset value of the
undervoltage. The relay can thus be used to activate a charger or generator.
Remote ON / OFF
You can connect a switch to the OFF terminal of the BG. If the OFF terminal is
connected to the Minus the BG will immediately switch off the attached devices.
If the switch is opened again, the BG will switch on again after about 1 seconds.
Since the current through the switch is zero (<10mA) a small switch can be used.
Battery Watch (optional)
As can be seen in the connection diagram, there may be an optional Battery Watch
connected. This is a simple battery status monitor which, by means of 3 LEDs,
indicates the status of the battery. Please contact your dealer.
PROGRAMMING
To start the programming mode a connection must be made between the
ProgramInput and Input+. The LED will flash. The number of flashes indicates the
program position (see table) that the BG is in. As soon as the desired program
position is reached the connection (between the ProgramInput and the Input+) must
be broken. As confirmation the BG will repeat the number of flashes. If it does not
match your selection, you can repeat the steps.
There are two types of settings that can be applied. Positions 1 to 10 adjust the
threshold and reset values for an under voltage alarm and the operation of the alarm
can be set with positions 11 and 12. These settings must be made separately (one
after another).
When removing the battery voltage the programmed positions remain retained.
Once the programming is complete, the equipment can be connected. First
disconnect the battery connection, connect the equipment to the Output+ and then
reconnect the battery.
Note:
• Before programming first disconnect the equipment from the BG.
